IMPROVEMENT IN SPINNING-TOPS.

Specification forming part of Letters Patent No. 197,393, dated November2Q, 1877; application led Api-i1 27, 1871.

To all whom it may concern:

. Beit known that I, JOHN W. MURPHY, of the city of Baltimore and Stateof Maryland, have invented certain Improvements in Tops, of which thefollowing is a specification; and I do hereby declare that in the sameis contained a full, clear, and exact description of my said invention,reference being had to the accompanying drawings, and to the letters ofreference' marked thereon.

This invention relates to certain improvements in whipping-tops, or thatclass of tops which depend for their continued rotation on theapplication thereto of a whip or piece of iiexible material held in thehand of the operator. v

The said invention consists in a peculiar manner of loading an, ordinarywooden whipv ping or other top, for the purpose of increasing belt,secured withina groove extending around the same. The ring or belt is-of a practically triangular cross-section, and is preferably formed ofa metallic alloy easily fused. The said-ring is placed as 10W in thecylindrical portion of the top as possible, in order to lower the centerof gravity of the top, and thereby increase its tendency to retain itsvertical position while in rotation.

To prevent the metallic ring or belt from becomingloose within thegroove, I provide the said ring or belt with projections c, which areformed by the metal, While in a fused state, iiowing into depressionsextending from the triangular groove.

Having thus described my invention, what I claim as new, and wish tosecure by Letters Patent of the United States, is

In combination with the wooden top A, the metallic ring B, locatedexteriorly of the said top, and within a groove extendingcircumferentially of the same, substantially as and for the purposespecified. l

In testimony whereof I have hereunto sub scribed my name this 23d day ofMarch, A. D.
